I've not posted to this group previously, but I can't resist this one ;^)

That seems rather extreme, because the probablity that we are in a
"regular" "magical" universe is already vanishingly small and we would
truly be safe in ignoring it. Even the probability of observing a single
large scale violation of the laws of probability is vanishingly small.
("Magical" universes suffer from repeated large-scale

According to *our* laws of probability, that is.

But how can you make recourse to our laws of probability if there are
infinitely many universes which have different laws?

Isn't Frederico's original proposition based on assuming infinite
variability and duplication of probability theory amongst all level 1
universes?

So I would think that taking the assumption onboard means you cannot
argue we are 'probably' in one of the more common universes... since
'probably' changes from universe to universe.
